The inlet conditions | As part of this study, we therefore imposed the velocity in the inlet that is a function of the Reynolds number and temperature. |
The outlet conditions | Here the dynamic pressure is null, which means that the total pressure is equivalent to the atmospheric pressure. |
The walls conditions | Defaults these are conditions obtained via an exchange of the boundary conditions at the interface between the two solid-fluid domains of the annular space, between the fluid domain and the domain solid of the external tube which is in the one side a coefficient of heat exchange, and in the other side, a constant temperature imposed to the wall. Adiabatic conditions are placed on the interface between the two solid-fluid domains, between the fluid domain and the solid domain of the inner tube. |
